Ronald I will give some hints try after that... Do tell if you cant solve it with the hints:
upthrust at a given depth h = ??
Net force acting on the ball at a depth h=???
Now write f=md2h/dt2
can you solve it now?
Density of a liquid varies with depth P(ro)=ah. A small ball of density p0 is released from the free surface of the liquid. Then--
a>. the ball executes SHM of amplitude p0/a
b>. the mean pos. of the balll will be at adepth of p0/2a from the free surface.
c>. the ball will sink to a max. depth of 2p0/a
d>. all of the above
